Reaction Steps

A solution of ethyl 4-bromobutyrate (681 mg) in MeCN (5.0 mL) was treated with morpholine (0.61 mL) at rt. The reaction mixture was heated to 80° C. for 3 h and cooled down to rt. It was concentrated under reduced pressure, diluted with EA and the org. layer was washed with water and brine, dried over MgSO4, filtered and concentrated under reduced pressure. The title compound was obtained, without additional purification, as a yellow oil (643 mg; 96% yield).
